Principle of operation

When a short circuit is connected between a high-voltage circuit connected to the outside of the control cabinet 10 and the three main circuits 39, and a fire is started, the current passing between the two first circuit connecting blocks 25 is too large, so that high temperature is generated between the two first circuit connecting blocks 25, the sliding plate 26 is pushed to slide in the sliding groove 27 by the expansion of the air in the sliding groove 27, the sliding plate 26 slides to drive the two first circuit connecting blocks 25 to separate, and a part of the expansion of the air in the sliding groove 27 enters the rear side of the conical head column 29 through the first connecting channel 28 to push the two conical head columns 29 to further separate the two first circuit connecting blocks 25. In order to open the circuit, two first circuit connection blocks 25 divide the back and drive first rotation axis 21 through first torsional spring 22 to first rotation axis 21 rotation elasticity and rotate, and first rotation axis 21 rotates and drives the electric wire and remove, makes the electric wire remove in fixed plate 20, puts out a fire to the electric wire that probably catches fire through the electric wire friction. When the first circuit breaking assembly 19 does not timely prevent the electric fire generated by the external electric wire 18, the fuses 34 between the four second circuit connecting blocks 33 in the second circuit breaking assembly 23 connected among the three sub-group circuits 38 are blown by the high temperature of the electric wire, so that the four second circuit connecting blocks 33 are separated and broken; fuses 34 among four second circuit connecting blocks 33 in a third circuit disconnecting assembly 30 of circuit connection in each group circuit 38 are blown by high temperature of electric wires, so that the four second circuit connecting blocks 33 are separated and disconnected, a second rotating shaft 35 drives the electric wires at the rear sides of the four second circuit connecting blocks 33 to move in the inner wall of the control cabinet 10 through the rotating elastic force of a second torsion spring 36, possible fire of the electric wires is extinguished through friction, the electric wires are moved into a dry powder cavity 37, and rapid fire extinguishing is carried out through dry powder.

When at least one small group circuit 38 in the control cabinet 10 is on fire, the sensing slide block 45 senses the fire in the control cabinet 10, so that the sensing slide block 45 slides in the pressure cavity 46 to extrude the solution in the pressure cavity 46 to the lower parts of the plurality of hydraulic telescopic rods 50, then the solution below the hydraulic telescopic rods 50 is controlled by the plurality of pressure stabilizing valves 51 to simultaneously enter the plurality of hydraulic telescopic rods 50, the plurality of hydraulic telescopic rods 50 simultaneously stretch out to push every two first slide blocks 48 to move towards the middle, and the two first slide blocks 48 move towards the middle to drive the telescopic assembly 47 to move to stretch out to match with the two second slide blocks 49 to slide in the sealing plate 40 to push the sealing plate 40 to move.
